Fast National ratings for Monday, July 21, 2014.

A season high for "MasterChef" and a solid premiere for "Hotel Hell" helped FOX win Monday among young viewers, while "The Bachelorette" drew Monday's biggest audience and led ABC to an overall nightly win.

And yes, that means that "The Bachelorette," airing its "The Men Tell All" episode, moved ahead of CBS' "Under the Dome" in total viewers as the Stephen King adaptation slipped to series lows. [Multiple TCA ratings panels this week have me conditioned to tell you that "Under the Dome" will certainly move ahead of "Bachelorette" once Live+3 numbers are factored in, which doesn't change the steadily dropping L+SD numbers for last summer's breakout hit.]

Monday also saw a bump for "American Ninja Warrior," which received an avalanche of publicity this week courtesy of Kacy Catanzaro. And while The CW's rearranged Monday gave "Whose Line Is It Anyway?" a bump, the comedies "Seed" and "Backpackers" are effectively DOA.

On to the numbers...

Among adults 18-49, FOX averaged a 1.8 rating for Monday night, tops in the key demographic. NBC was second with a 1.6 key demo rating, holding off ABC's 1.5 key demo rating. CBS was down to fourth with a 1.2 key demo rating, still far ahead of the 0.4 key demo rating for The CW.

Overall, though, ABC topped Monday with 5.735 million viewers and a 3.9 rating/7 share for the night, ahead of the 5.12 million viewers and 3.3/6 for CBS. FOX and NBC both averaged a 2.9/5, with FOX drawing 4.925 million viewers, edging out the 4.91 million viewers for NBC. The CW averaged 1.09 million viewers and a 0.7/1 for the night.

The CW's new "Whose Line Is It Anyway?" and a "Whose Line" repeat averaged 1.73 million viewers and a 0.6 key demo rating.
